I have two suits. One is home made, and the other was purchased at a gun show, made by a former special forces soldier. Granted, I don't use them often because they are so hot.
The home made suit was made by my mother. Essentially, she took a bath robe and duplicated it in a camo fabric. Then I took camo burlap and sewed strips about a foot or so wide on the suit. These pieces were then cut vdrtically, sort of like a fringe, into strips (after being attached to the "bath robe" base) that varied from 1 2/2 inch to bout 3 inches. These strips were sewn on, overlapping like roofing shingles. All closures are done in velcro. Leggings were also made this same way. I think this one is more effective than my other suit.
The "military" style is a standard two piece construction. All the covering is made of bundles of varying colors of twine. It works well, but I just like the one Mama made better.
If you sit still, you will disappear with either of the suits you are considering. Therefore, in my opinion, with whatever one you choose, you will become invisible. Just make those adjustments needed to handle the bow well.
In my opinion, the ghillie suit is best suited to stand hunting in ambush mode. Any kind of suit will get tangled in the thick stuff as you move around.
